Bring out the sweet side of Halloween with these colorful sugar cookies, a real treat for your favorite little tricksters. Kids will be happy to help out with this playful recipe—invite them to roll the balls of dough in colorful sugar.
Preheat oven to 350 degrees. In a medium bowl, whisk together flour, baking soda, baking powder, and salt; set aside.
In a large bowl, using an electric mixer, beat butter and granulated sugar until light and fluffy. Add egg and vanilla; beat until combined. With mixer on low speed, add flour mixture; mix just until combined (do not overmix).
If using two colors of sanding sugar, place each in a separate shallow dish (or combine them in one). Roll dough into balls, using 1 1/2 tablespoons for each. Roll in sanding sugar, pressing lightly to coat completely. Insert a wooden stick in center of each ball; place on baking sheets, about 1 1/2 inches apart, with wooden sticks lying horizontally. Lightly press down on each ball with the bottom of a glass to flatten slightly.
Bake until edges are golden and crisp, about 20 to 25 minutes. Transfer cookies immediately to a wire rack to cool completely.
Switch colors, and bake these cookies all year long: Try red and green sprinkles or sugars for Christmas; red, white, and blue in July; pastel and primary colors anytime.
